Potassium bicarbonate
Cas no.:298-14-6
Property:
Potassium Bicarbonate is colorless and transparent crystal. The relative density is 2.17. It is stable in the air. It is soluble in water, forming a slightly alkaline solution, but insoluble in alcohol. The solution can not react with magnesium salt yielding precipitate of alkaline salt. It begins to decompose at 100° C and completely decomposes and turns into Potassium Carbonate losing carbon dioxide and water at 200° C.
Packing:
Plastic woven bag or kraft paper bag inner with plastic bag, in 25/50/500/1000kg net.
Handling and Storage:
Store in dry and ventilated house away from moisture. Don't store in goods yards or expose to the air. Protect the material from rain when loading and unloading. Be sure to keep the package dry and free from contaminant. Avoid handling and transporting together with acid substances. In the event of a fire, use water as extinguishing agent.
Applications:
Potassium Bicarbonate is used as a raw material producing potassium carbonate, potassium acetate and potassium arsenite. Also it is a fire-extinguishing agent for oil and chemicals. It is used in medicine and baking powder.
